1. A method of mitigating fuel in oil in an internal combustion engine of a hybrid electric vehicle, the method comprising:
detecting events in which the engine is on for less than a predetermined engine on duration and a temperature of engine oil in the engine is below a predetermined temperature for the engine on duration;
counting the detected events;
when the number of detected events counted reaches a threshold count value and a vehicle speed exceeds a threshold vehicle speed value, running the engine for a predetermined warm up duration or until the temperature of the engine oil exceeds a predetermined warm up temperature.
